Question

3x-9y=63
2x-6y=-18
Solve system of equations by graphing then classify as Independent on dependent and consistent or inconsistent?

Answer 1

Without any work, I can see that each line has a slope of 1/3.

So you will have two parallel lines, which of course will not meet.
So what classification would the system fall under?

Answer 2

Consistent and independent?

Answer 3

Yes, they are independent, because one equation cannot be derived from the other.
But they are inconsistent, since there is no solution.
